"By 'world religions,' we understand the five religions or religiously determined-systems of life-regulation which have known how to gather multitudes of confessors around them. The term is used here in a completely value-neutral sense. The Confucian, Hinduist, Buddhist, Christian, and Islamist religious ethics all belong to the category of world religion."
